vThe lframe .15 of my improved device coinprises legs 16 and an innerspider 17 fixed to the legs,the legs supporting the sector 18 of aringat the tops thereof for connecting'the upper .ends of ,the legs vandforming a sectormember within which the bowl is received.

The bowl 21 is provided with an annular trough 22, which isajmeat-receiving trough, in which the meat is contained and reduced. Thetrough is arceshaped in' cross-section. The 'outer rim 23` of the bowlis provided with an annular Vface 24 which coacts with a 25 on abearing-sector 26 for lsaid. outer edge, to form a. joint at the sidesand rear 'of the bowl to prevent seepage olfleakage of themeat and itsjuices over the edge of the bowl.

A. cover 2 9 is received above the bowl. The bearing-sector 26 is fixedto theunder face of said cover, as by a dove-tail joint 30, andpreferably extends throughout the lower face of said cover jointbetween' the outer peripheral edge of said bowl and the lower face ofsaid cover throughout theeXtent of the latter.

member 18 ofthev main frame'by having lugs 31 supported by saidsectonineinber. and secured thereto by bolts 32 and being provided withan arcuate flange 33 supported by said sector-member and securedtheretoby bolts .j The cover is provided with an opening 37 throughwhich the knives 38 operate in the ,cutting operation. The wall of theopening i s pi1ovided with` a flange 39. A hood 40 for are locatedbetween the g and foi-in spaces-56 between the inner ends of l on, thecomb being `nient of to forma close running Thevk cover is preferablysecured to the sector- 'thereto yin a bearing 71, vnection 72, a flange73 of said bearing-'sleeve the knives is received over said knives andis provided with lflanges 41. Latches '42 are pivoted on bolts 43 inbearings 44 in theV bearings 48 in the iiange 373.

A comb 51 is received"insaidl opening and preferably comprises side.filling-pieces 52 atf'tlie'4 respective sides of the knives.Teethl;53.:are.received in the spaces between the knives, their innerends substantially meeting the outer peripheries of the collars 5ibetweenthe knives. {Spacing strips 55 bases of the teeth the teeth inwhiclithe knives operate. The Y side filling-pieces, .they teeth and thespacing strips are preferably connected together by rivets 57 to form arigid comb. The comb is slidablel into the opening fromthe rear, as bymanipulation with a handle58 thereliXed in place by a setscrew 59threaded into the plate 46.V

The forward end of the cover is provided with a strengthening flange 62.This .flange is anl upturned llange and directs the meat in-to thebowlgand crosswise of the trough.v At the middle fordepresses andrspreads it wardportion of the cover there is a boss 63,

providedwith a hole 64, in which a shaft 65 isv looselyv located. Thisboss is shown as merging .into the flange foimed atthe wall of theopening 37 and into the flange 62 at the front vof the cover.

The bowl is provided with an inner raised hub 67, the side inner orrotating of which is4 formed as part of the bottom face ofthemeat-trough, the knives coacting therewith in lcutting 'themeat,thereby increasing the cutting sur- .iace.- This hub and coactingmeat-supporting surface thereof preferably surround the shaft.The'frusto-conoidalportionsurrounding the shaft formsva shield betweenthe knives and ,thejoperatoig whose position is at thefront of themachine, and is an elesafety in the machine and aids in forming .aclosed channel in which the knives operate. The cover 29k is receivedabove this hub. The boss 63 of the cover is in line with the hub 67, theshaft being received locselyfthrough both.

The upright shaft 65 has the bowl fixed of a key-coiinectionA 69. Theshaft rotates in a l'iearing-sleeve with which it has screw-conbeingprovided with holes 74'for reception of a suitable pin-wreiich forrotating the bearingsleeve. The bearing-sleeve is arranged to be lockedin adjusted positions by preferably of frusto-conoidal forni,l

for rotation therewith, as by means 7 O adjustable up and down forthesuet,-stearin, ltallow, fats Aand con- Vgealable constituents in the`meat or meatdouglrt-ogadhere. tothe inner face or bottom ofthe bowl,forming a layer onrsaid f bott-om; These fatty substances therebysepproduct;`

aratev from the-meat.

In order to counteract such separating tendency: of the fattysubstances, and to again mix the same with the meat, vand to 'ft insureproper mixture of the fatty substances with the meat, Iprovide means forscraping the inner bottom .face .of the annular trough inythe bowl andfor urgmg said fatty substances among the meat constituents of thebowlthereby permeating fthejmeat, preventing undjueleanness in themeat-dough and makingit more juicy and valuable. and avoiding fattylumpsin the Iliave shown thisaccomplished byl means of; afscrapery 135,exemplified as a flexible metal band,-forzinstance of steel, ofa formcomplemental tothe Vcrossfsectional* arcuate form ofthe inner orfbottomface of the annular n'xeat-trough in the bowl.

The direction of rotation of the bowl is indicatedbythe arrow a, andthel direction ofv rotation of the knife-blades is in- ,dicated byzthe`arrow b. v y

I: prefer that the edge of the scr-aper presentedv toward; theapproaching adhering substances in the bottom ofthe bowl n, shall besomewhat' 1 sharpened, as indicated `at136 preferably invmannertosdirect the layer of fatty tsubstancesaway from'the botat 13.7.in Fig.1.4iY 'i r i v The scraper is Vindicated asa iiexible band,

tom-ofthe-bowhv as indicated for instance `oneend ofwhich-is providedwith-a holding clip 140l shown secured to thescraper-band by means of`rivets 141 and as/iixed to the forward :flange of the coverby a bolt142. The other end ofv the scraper band is provided with a clip 143,fixed to the band, as byv rivets144, and provided with a threaded shank145. The threaded shank isadjustablein bearings 146 ofa bracket 147fixed to d the mainframe, as'byV bolts 148. Nuts149,

150, are threaded about the shank, the shank passingvloosely throughsaid bearings.

Adjustments of the nuts along said` shank .canse movement of thescraper-blade toward the inner orbottom face ofi the meat-trough so asto.' hug the meatftrough, or away from said inner or bottom face so asto prevent undue lfriction between saidy iiexible band `and said inneror bottom face.

bottom of the same, and are shown vintegral withthe scraper-blade. VTheyare preferably `of plow form, soas tor move the meat awa-y from thebottom and turnl the same over similarly to the action ofv a land-plow,foi-,the purposeofmixing the` meat and of moving the fatty substances`thereof into the interior of the meat-body. These deflectors deiect themeat while tlie latter is passing thereover alongl the path of'itsmovement and vthe knivesV aid in mixing-the meat in directionscrossivise of said path. A The directions of rotation of theuknives 'inthe present instance have a tendency to move the body yof meat towardthe outer trough inl order to deflect the meat *inwardlyVv away from:saidl outer wall, said defiector Thesef may. be of suitable number .andsuitably placed across ythe meat-trough, preferably adjacent tothehaving a defiecting faceextending inwardly and in thev direction oflrotationof the bowl, being provided with an upper Wall 159Kv for ,aidingin the deflection of the meat. This deflector acts complemental.- to thefirstnamed defiectors to mix the meat.

The meatat the inner portion ofthe annular trough is in practice morefinely `divided by the knives thanthe meat at the outer portion of saidannular trough, lfor the reason that there is a less body of lmeat atsaid inner-portionl than at said. outer portion, due to the increasingdiameter of the; bowl, thesame amount of cutting edges of the knivesacting on saidinnerfportion as on said outer portion, and'therev is inpractice a certain portion of the finely Idivided meat which adheres tothe inner `wall of the trough and is 'located in adjacency thereto, andwhich is not readily carried .to the outer edge of the trough bytherotary action of the knives. 1 y' JIn. orderto ai'dthe mixing of thefinely divided meatwith the coarser lcut portions of the meat, I providea deflector v161, which has. a .wa-11,162 in adjacencyto the knives,

and preferably has an inner edge H163V of such form as to substantiallycontact the inner portionof the wall of the annular trough. It may 'havean louter flange 164.
